Ice quality: Good at first. But they didn't cut it during my time there, and it got worse. Also, they blocked off 1/4 of the rink for stick and puck during a public session, which was odd and a bit annoying. At least it was an edge and not the center. Roughly NHL sized.
Building: Very well decorated. It's got a cylindrical ceiling. The lighting was great. The music was tasteful.
Bathrooms: Good by ice rink standards.
Location: Very easy to find in the center of the botanic garden. Parking is fine. The town is known for skiing and bungee jumping.
Price: 15 NZD= 10 USD, which is quite cheap for Queenstown. Most activities there cost $200.
Snack bar: Food and alcohol. Also pleasantly decorated.
Overall: Worth visiting if you are in the area.
